An ignition scope pattern of the ignition secondary shows the firing line at 28 kV. This indicates ________.
A) high resistance in the secondary ignition circuit
B) a too wide spark plug gap
C) a normal voltage reading
D) Either B or C

Question

Quizplus · Accepted Answer

A firing line at 28 kV can indicate either a too wide spark plug gap, which would require a higher voltage to bridge the gap, or it could be considered a normal voltage reading depending on the specific vehicle and conditions. High resistance in the secondary ignition circuit would typically result in a higher than normal firing line, but the interpretation of 28 kV as high depends on the context of the vehicle's normal operating parameters.
